Is Not Abstract Error

[hosker666]

Hi, I am new to Java.

I have looked on this forum and seen other people with this error and the solution seems to be to add the method.

however, i am certain i already have can someone tell me what is going wrong here??

ERROR:

src\minecraft\net\minecraft\src\mod_plasmariteGem.java:113: error: mod_plasmariteGem is not abstract and does not override abstract method getTransferLimit() in IElectricItem public class mod_plasmariteGem extends BaseMod
                                                  ^

I am using Eclipse as my IDE and using the following commands to compile:

@echo off
runtime\bin\python\python_mcp runtime\recompile.py %*
pause

Found in a batch file as part of MCP (Minecraft Coder's Pack)

any help would be amazing! thank you!

Hello,

The error because your class mod_plasmariteGem does not have the implementation required by the IElectricItem interface. You have the methods from this interface in your code but you place them inside the ItemplasmariteGem class.

Ah thank you I will change that and get to back to the forum if it works

Hi, yeah I am really struggling to work out where i need to put the method now. This is my first piece of java and i am self-taught so please forgive me if i am being really dumb! Can somebody please suggest to me how i should arrange this code so that it will work??

thanks

[wsaryada]

Your code is like this:

public class mod_plasmariteGem extends BaseMod implements IElectricItem {

    static class ItemplasmariteGem extends Item {
        public boolean canProvideEnergy() {
            return true;
        }

        public int getMaxCharge() {
            return 1000000000;
        }

        public int getTier() {
            return 3;
        }

        public int getTransferLimit() {
            return 500;
        }
    }
}

These methods inside the ItemplasmariteGem class above should not be there, because these method are methods defined in the IElectricItem interface. It should be in the scope of mod_plasmariteGem and not in ItemplasmariteGem.

Hey thanks, yeah i was implementing to the class when i should have been implementing to the object. Fixed it by moving the implementation to

static class ItemplasmariteGem extends Item implements IElectricItem{
